Nutrient and sediment loss from a Niagara County watershed : the east branch of Twelvemile Creek, May 1998 to May 2000Discharge and nutrient loss from a Niagara County tributary, Twelvemile Creek, was intensely monitored for two consecutive years by automated gauging and sampling techniques. This report focuses on the two annual cycles monitored (19 May 1998 to 18 May 1999 [Year 1] and 19 May 1999 to 17 May 2000 [Year 2]). The sampling regime allows an accurate measurement of discharge, nutrient and soil loss from a watershed during hydrometeorological events and nonevent conditions. Discharge and concentrations of nitrate, total phosphorus, sodium, total suspended solids, and total kjeldahl nitrogen were measured and converted into the amount of material lost from the watershed or loading to Lake Ontario.
